To determine the work done by each person, we need to calculate the amount of work done by the force applied and the distance moved.
For Charlie, the work done is:
Work = force x distance = 500 N x 1.2 m = 600 J
For Lauren, the work done is:
Work = force x distance = weight x height = (500 N) x (5 m) = 2500 J
Therefore, Lauren did more work than Charlie. The answer is option a) Lauren did more work.
Charlie lifts a box with a force of 500 N and sets it on a table top 1.2 m above its starting position. Lauren pushes an identical box up a 5 m ramp from the floor to the top of the same table. Which person did more work?
a
Lauren did more work.
b
The size of each girl needs to be known to find the answer.
c
Charlie and Lauren did the same amount of work.
d
Charlie did more work.
